Plot details are being kept under wraps, but “Arms” focuses on Lancelot and his adventures after the breakup of Camelot.

Echo Lake is hoping to attract a filmmaker that can give the movie a distinct visual style.

The company also is looking at “Arms” as a step into larger commercial projects, continuing a path begun with “The Ward,” a ghost thriller directed by John Carpenter and starring Amber Heard that is in postproduction. It also is developing action script “The Prince,” by Jeremy Passmore and Andre Fabrizio, to act as Carpenter’s follow-up.

Aperture is in preproduction with MPCA on “Sex Ed” starring Haley Joel Osment. It is developing “The Last Witch Hunter” at Summit and “The Brood” at Spyglass, with Breck Eisner directing.

Lott wrote the script as a spec that made the rounds, and while it initially didn’t sell, it got him an assignment to adapt, with “Priest” writer Cory Goodman, the IDW comic “Lore” that’s being produced by Andrew Lazar.
